The inner walls of the two fixing plates 102 are threadedly connected to the outer walls of the near ends of the two plug pins 104 respectively. The outer walls of the near ends of the two plug pins 104 are movably inserted into the inner walls of the two limiting blocks 103 respectively. When it is necessary to replace the indentation roller, only need to rotate the plug pin 104 to loosen the fixation between the limiting block 103 and the indentation roller, then the new indentation roller can be easily taken out or installed. By inserting the plug pin 104 into the limiting block 103, it is ensured that the indentation roller remains stable during the working process.
[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the transmission part 2 includes a transmission shaft 201, a connecting rod 202 and a limiting rod 203. The number of the connecting rods 202 is set to eight. Every four connecting rods 202 form a group. The outer walls of the transmission shaft 201 far from both ends are fixedly welded to the outer walls of the two groups of connecting rods 202 respectively. An installation groove is opened on the inner wall of the transmission shaft 201 near one end, and a limiting groove is opened on the inner wall of the transmission shaft 201 near the center. The installation groove is communicated with the limiting groove, and a sliding groove is opened above the limiting groove. The inner wall of the installation groove is threadedly connected to the outer wall of the limiting rod 203. The outer walls of the transmission shaft 201 near both ends are rotatably connected to the inner walls of the two fixing plates 102 respectively. When the external power source drives the transmission shaft 201 to rotate, the connecting rods 202 will also rotate together.
[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the roller part 3 is composed of a roller cylinder 301 and an indentation block 302. The inner wall of the roller cylinder 301 is movably abutted against the outer wall of the indentation block 302. The outer walls of the roller cylinder 301 near both ends are fixedly welded to the outer walls of the two groups of connecting rods 202 respectively. A receiving cavity is opened on the inner wall of the roller cylinder 301 near the front. A sliding cavity is opened on the inner wall of the roller cylinder 301 near the front of the receiving cavity. The required indentation pattern or mark can be formed on the surface of the material through the indentation block 302.
[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the locking member 4 includes a connecting column 401, a connecting block 402, and a mounting column 403. The bottom end of the connecting column 401 is fixedly welded to the top of the connecting block 402. One side of the connecting block 402 is fixedly welded to one end of the mounting column 403. The outer wall of the connecting column 401 is slidably connected to the sliding groove. The outer walls of the connecting block 402 and the mounting column 403 are slidably connected to the inner wall of the mounting groove. One side of the connecting block 402 away from the mounting column 403 is movably abutted against one end of the limiting rod 203.

Then, by rotating the limiting rod 203 to move it towards the center direction of the transmission shaft 201, the limiting rod 203 and the connecting block 402 are in close contact to achieve the locking of the indentation block 302. When the indentation block 302 is in the locked state, it can ensure that the position of the indentation block 302 remains unchanged when the roller barrel 301 rotates, so as to stably form an indentation on the material. When it needs to be disassembled, by adjusting the limiting rod 203, the indentation block 302 can be conveniently released to separate it from the roller barrel 301, which provides convenience for the replacement and maintenance of the indentation block 302 and makes the operation simpler and faster.
[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the locking member 5 is composed of a spring 501, a locking block 502, and an adjusting rod 503.

The outer wall of one side of the locking block 502 is slidably connected to the inner wall of the accommodating cavity. The outer wall of the other side of the locking block 502 is slidably connected to the inner wall of the indentation block 302. The outer wall of the adjusting rod 503 is slidably connected to the inner wall of the sliding cavity. When the indentation block 302 needs to be disassembled, after the indentation block 302 is installed, the locking block 502 moves into the interior of the indentation block 302 under the elastic force of the spring 501 to lock it and prevent it from moving. When the indentation block 302 needs to be adjusted or replaced, the adjusting rod 503 can be toggled to make the locking block 502 leave the indentation block 302, thereby releasing the indentation block 302 so that it can be moved or replaced.
[0027] The usage method and advantages of the present utility model: When this indentation roller that is convenient for replacement is working, the working process is as follows:
[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the indentation block 302 needs to be replaced and maintained, the adjustment lever 503 can be toggled to make the locking block 502 leave the indentation block 302. At the same time, the limit lever 203 can be adjusted to conveniently release the indentation block 302 and separate it from the drum cylinder 301. After replacement, the connecting block 402 and the mounting post 403 are placed in the mounting groove, and the connecting column 401 is pushed to completely insert the connecting block 402 and the mounting post 403 into the mounting groove. Then, by rotating the limit lever 203 to move it towards the center direction of the transmission shaft 201, the limit lever 203 and the connecting block 402 are in close contact to lock the indentation block 302, which provides convenience for the replacement and maintenance of the indentation block 302. Without the need for complex tools or steps, the operation process is simple and fast, reducing the downtime and operation cost, and improving the work efficiency. Through the close contact between the limit lever 203 and the connecting block 402, the initial locking of the indentation block 302 is achieved. The locking block 502 moves into the interior of the indentation block 302 under the elastic force of the spring 501 for further locking, enhancing the firmness and stability of the locking. The double locking mechanism ensures that the indentation block 302 will not shift due to rotation during the working process, guaranteeing the accuracy and consistency of the indentation.
